Lactone formation by rhodium-catalyzed C-C bond cleavage of cyclobutanone

As a coordinating ligand, the phenol group in appropriately substituted cyclobutanones facilitates the Rh1-catalyzed activation of the C-C bond between the carbonyl group and the α-carbon atom. This novel reaction leads, depending on the position of the phenol group on the cyclobutanone ring, to lactones of varying ring size (for example, as shown for a seven-membered-ring lactone).
